CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 773,158, dated October 25, 1904.-

Application filed April 28, 1898.

To all whom it may concern:

Be it known that I, ALBERT PFAFF, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey,

have invented certain new and useful Improvements in Cash-Registers, of which the following is a specification.

My invention relates to various new and useful improvements in cash-registers, and more IO particularly to the adding mechanism thereof; to the connections between the keys and an operating device, such as a movable tillcover, for actuating the adding mechanism; to the mechanism for manipulating the tablets; to the mechanism for locking the keys, as will allow for the release of a key erroneously depressed and the depression of the correct key, and to other details of construction, which will be specifically referred to hereinafter.

My improvements are designed for especial use in connection with a cash-register of the Osborn type, wherein a stationary till is provided with a movable till cover normally locked in a closed position, but adapted to be unlocked by the depression or other manipulation of a key or keys, the movement of the till-cover in the disclosure vof the till serving to elevate a tablet-actuating bar or rod in the path of movement of which the desired tablet or tablets have previously been positioned by the depression of the key or keys. My invention may, however, be employed in connection with cash-registers of other types,- and different features of the invention may also be utilized, either singly or in the aggregate, in connection with cash-registers and analogous computating or mechanical mathematical instruments or machines.

WVhen the improvements are used in the aggregate in connection with a cash-register of the Osborn type, I prefer to arrange the keys in several banks,'representing, respectively, units, tens, and hundreds, or more or less of such denominations. These keys are mounted on a shaft extending longitudinally of the machine. Mounted adjacent to the keys, and preferably above the same, are the counter- Serial No. 679,098- (No model.)

, operating devices, one for the units, a second for the tens, and a third for the hundreds. These counter-operating devices comprise, preferably, each a semicylindrical shell car- .ried on radial arms mounted upon a shaft exing lengths. These arms or levers correspond in number with the keys in each bank, and each of them carries a finger or hook projecting through an opening in the semicylindrical shell of the counter-operator. These projections or hooks when the counter-operator shell occupies its normal position are located in different planes of uniform graduation, the hook or projection corresponding to the key of the highest denomination occupying the lowest plane, while that of the lowest denomination occupies the highest plane, the intermediate hooks or projections occupying equidistant planes between the two extremes. The keys of the cash-register are each connected with an actuating-lever which may be engaged with the particular arm or lever of the register-operator, whereby upon. the depression of any key the corresponding arm or lever of the register-operator will be moved toward the semicylindrical shell thereof to project the corresponding hook or projection outwardly from said shell. The keys are each provided with a projection thereon, which when any key is depressed will engage behind a spring-pressed locking-bar to hold the key in a depressed position. When, however, any other key of the same bank is depressed, the lug, before it can engage behind said lockingbar, will elevate the latter so as to release any other key which may be locked by said locking-bar. In this way if a key is erroneously depressed in any bank it can bereleased by the simple depression of the proper key in the same bank, or if a key in a wrong bank has been depressed it can be released by simply depressing any other key in the same bank to an extent sul'licient to release the improperly-depressed key, but not to result in the locking of the other key. Each key of the cash-register is also provided with an outwardly-projeeting arm or shoe, as in cashregisters of the Osborn type, which arm or shoe will engage with a suitable trip of the proper tablet-rod and move the said trip into a position coincident with the path of movement of a tablet-elevating bar, the latter, in cash-registers of the class under consideration, being elevated and depressed by the movement of the till-cover. hen, therefore, any one or more keys have been depressed, the trips of the corresponding tablet-rods will be actuated, whereby upon the elevation of the tablet-elevating bar by the movement of the till-cover the proper tablets will be elevated, being locked in their uppermost position by a suitable locking-bar, which is released by the depression of anyone of the keys when a new sale is to be registered. The said tablet-elevating bar also carries one or more cams, which, near the completion of the stroke or movement of the till-cover or other counter-actuating device, engages a cam-arm carried by all of the locking-bars for the keys, whereupon all the keys which may have been depressed will be released near the completion of the movement of the till-cover and be returned to their normal positions by proper actuating-springs-as, for instance, by means of the rod or bar which controls the position of the locking-bar for the tablet-rods. The hooks or projections of the semicylindrical shells comprising the counter-operator are normally out of the path of movement of a rod or bar which is carried on radial arms to the same shaft on which said shells are pivoted, whereby said bar or arm moves concentrically to said shells, being operated always to its full stroke by the movement of the till-cover or other hand-operated device. WV hen, however, any one or more of said hooks or projections have been operated by the depression of one or more keys to project beyond the periphery of the counter-operator shells, the said hook or books will extend in the path of movement of the concentrically-swinging bar or red to be engaged thereby. The moment of engagement between the said bar or rod and any one of the hooks or projections depends, manifestly, upon the particular hook or projection under consideration, or, in other words, upon the plane which it may occupy. W hen, therefore, a hook or projection has been operated by a key of the highest value, it will be engaged by the concentrically-swinging bar almost immediately after the latter commences to move, while, on the other hand, if the hook or pro jection has been operated by a key of the lowest value it will not be engaged by the coneentrically-swinging bar or red until the latter has almost completed its movement. The engagenient between theconcentrically-swinging. bar or red and any one of the projections or hooks will result in the movement of the corresponding shell or shells to an extent dependent upon the particular book or projection which may have been operated. Upon the return movement of the concentrically-swinging bar or rod the shell or shells which may have been operated will be returned to their normal positions by means of their operatingsprings.

The varying movements of the semicylindrieal shells are utilized in elfectii'ig a totalizing of the amounts registered by mechanism which preferably cooperates with a totalizing-register of novel construction. This register comprises a series of disks mounted loosely on a shaft and representing units, tens, hundreds, thousands, and any desired higher denominations. Each disk is provided on its periphery with the nine digits and a cipher arranged in sequence. Either the shaft coincident with each disk or each disk is provided with a pawl on its interior adapted to engage with a tooth or lug carried by the other, whereby upon rotating the shaft in the proper direction the pawl of or for each disk will engage with the tooth or lug at a point corresponding to the same figure on all the disks, so that upon rotating the shaft the disks will not be turned until this engagement takes place, the engagement taking place obviously only when the same figures on the several disks are in line. This allows for a quickand easy resetting of the register when desired. The units-disk is driven through suitable gearwheels from a pawl-carrying arm actuated by the semicylindrical shell of the units-bank, the extent of movement of said units-d isk depending upon the movement of said shell and the movement of the latter depending, as stated, upon the identity of the key depressed. 1n carrying from the units to the tens disk, from the tens to the hundreds disk, and from the hundreds to the thousands disk I employ suitably-arranged pawls, one for each carrying operation. These pawls are arranged behind the disks and are preferably carried on swinging arms having rearwardly-extending cam-surfaces. The carrying-pawls are normally held in an elevated position, so that when they are actuated they do not engage with the driving-ratchet of the next disk. For this reason it is possible to actuate the swinging arms carrying the pawls at each movement of the till-eover or other hand-operated element. In order to do this, I mount behind the swinging arms a shaft carrying rotating cams which engage successively with the rearwardly-extending cams of said swinging arms to effect a successive operation of the latter. The said shaft carrying the camtingers is operated, preferably, upon the return movement of the till-cover by a pawl connected with the tablet-elevating bar or red. The carrying-pawls are held in the normally elevated position by means of small plungers carrying pins engaging beneath the pawls and each normally elevated by means of a small latch, a spring being employed tending to depress each plunger. One of the gearwheels which operates both the units, tens, and hundreds disks is provided with one or more pins which engage the said bolts or latches to release the same to trip the desired plungers when the disk of the lower order has reached or has passed the tens or cipher and it is desired to carry to the next higher order. This therefore allows the proper carrying-pawl to drop and engage with the operating ratchet or gear ofthe disk of the next higher order, whereby the finger-cams in rotating will operate the pawl to positively advance the latter disk one step forward. The pawl is preferably so arranged that upon its return movement it positively elevates its corresponding plunger and resets the same. The tens-disk will be properly geared to and will receive movement from the swinging shell of the tens-bank of keys, whereby any key depressed in that bank will result in the operation of the tens-disk and the disks of higher order without affecting the units-disk. The hundreds-disk is connected to and receives motion from the swinging shell of the corresponding bank of keys, so that upon the depression of any one of the latter keys the h und reds-disk will be advanced to operate the disks of higher order, but without affecting the tens or units disks. The disks of the register higher in order than those which are capable of direct operation through the instrumentality of any key and which hence do not have to be capable of independent operation are operated from the hundreds-disks by means of a simple carrying device under the control of a single one of the actuatingpawls, as will be more fully described. I

In order that my improvements may be better understood, attention is directed to the accompanying drawings, forming a part of this specification, and -in which Figure 1 is a vertical sectional view of a cash-register of the Osborn type, showing the preferred embodiment of my invention applied thereto. Fig. 2 is an enlarged front elevation of the register, the units-keys, the tens-keys, and the connecting mechanism; an enlarged sectional view of two keys and the connections between the same and the register and tablet-rod; Fig. 4, an enlarged plan view of the register; Fig. 5, a section on the line m m of Fig. 4; Fig. 6, a longitudinal section through the registeringdisks, and Fig. 7 a or oss-section showing the parts in the closed position,

In all of the above views corresponding parts are represented by the same numerals of reference.

1 represents the inclosing casing of a cashregister of the Osborn type, provided with a till 2 therein, protected at the back by a stationary partition 3 and adapted to be covered by a movable cover 4, carried on webs 5 at each side, which webs are pivoted on a shaft 6. The tillcover may be operated by a handle 7 and is provided with any well-known and suitable means for maintaining it normally in a locked position when closed, butfor releasing the same upon the depression of a key. The webs 5 at the sides of the till-cover are each connected to a link 8, each of which is connected at its lower end to an arm 9, pivoted at 10 to the side of the cash-register frame. The arms 9 are bifurcated at their rearward ends, which bifurcated portions engage a rod 11, extending across the machine and connected at each end to slides 12, working between suitable guide-lugs 13. The slides 12 are connected at their upper ends bya tabletelevating bar or rod 14;, made, essentially, right angular in cross-section. elevating bar 14 is connected to the upper end of a spring 15, the lower end of which is attached to an arm 16, riveted to the bottom portion of the partition 3, whereby said spring tends to normally depress the tablet-raising bar and also to close the till-cover when the connections with the links 8 and the webs 5 have been moved out of line with the shaft 6.

17 represents one of the tablet-rods carryinga tablet 18 at its upper end, which tablet is adapted to be exposed through a suitable glass front at the top of the cash-register, as is common. The tablet-rod 17 is provided with a spring-tri p 19 at its lower end, adapted to be moved into the path of the tablet-raising bar 14:, but normally being held out of that position. The tablet in its raised position is locked by a tablet-locking bar 20, engaging beneath a lug 21 on the tablet-rod. The tablet-locking bar 20 extends entirely across the machine, so as to hold elevated any one or more of the tablet-rods,and is carried by arms 22, secured to the shaft 23, mounted in the side frames. The arms 22 at each side are prolonged toward the front of the machine and are connected from side to side by a rod 24, with which all of the keys 25 normally engage. The arms 22 may be extended downward at 26 and, as is common in the Osborn machine, may carry a projec' tion 27 near their lower ends, (see dotted lines, Fig. 1,) which projection may engage with a trip-lever 28, having a tooth 29,which engages with a toothed plate 30, carried on the webs 5 and by which the till-cover will be locked in its closed position.

The keys 25 are all mounted loosely on a shaft 31 and are provided at their inner ends with downwardly-extending curved arms 32, which engage the spring-trips 19 of the tablet-rods to move the same into the path of the tablet-elevating bar 14.

The keys 25 are arranged, preferably, in

. two rows and are grouped into separate banks,

The tabletwhich are designated in Fig. 2 by the letters 11,13, and O, portions of the two latter banks being broken away. These banks represent, respectively, units of cents, tens of cents, and units of dollars or, as hereinafter designated, hund reds of cents. The keys in each bank are numbered from 1 to 9, respectively, as is usual in machines of this class. Each of the keys is provided behind the shaft 31 with an upwardly-projecting lug 33, which when the key is depressed is adapted to ele vate a locking-plate 34:, which is drawn in behind the lug by a spring to lock the key in a depressed position with the curved arm 32 in contact with the trip of the tablet-rod. Eachbank of keys is provided with a separate locking-plate mounted on the shaft 23, so that first one key in one bank may be depressed and locked and subsequently another key in another bank may be depressed and locked. If, however, an improper key in a bank has been depressed, it may be released by depressing the proper key in that bank, which will result in the lug engaging beneath the locking-plate 3% to release the erroneously-depressed key and to allow the said locking-plate to engage behind the lug of the correct key. On the other hand, if a key in a wrong bank has been depressed it may be released by depressing another key in the same bank to an extent only sufiicient to elevate the lockingplate 34 from its engagement with the locked key. Each of the locking-plates 34 is provided with a downwardly-extending arm 36, carrying a cam-surface 37, with which a projection 38, carried by the tablet-elevating bar, engages near the end of the upward movement of said bar to elevate the locking-plates for the release of any key or keys which may have been depressed.

The improved cash-register is provided, preferably at its upper part, with. a suitable totalizing register of any desired type. 1 have, however, invented an improved totalizing-register, which will be fully described. The totaliZing-register is arranged to be operated upon the depression of one or more keys and to add to the sales already recorded the total represented by such keys. 1 actu' ate the totalizing-register by improved mechanism, which will now be described.

39 is a stationary shaft extending across the machine. Mounted upon this shaft are a series of semicylinc h'ical shells 4:0, one for each bank of keys, in the present instance three. These shells are carried on arms &1, and they occupy a normally retracted position by means of spiral springs L2, surrounding the shaft 39. Carried within each of the shells 4C0 are a number of curved concentric arms 43, pivoted to small brackets &4, depending "from within the shell. These arms a3 correspond in number to the keys. Each arm is provided with a hook or projection &5, which extends through the shell 10, but is normally held in contact with the exterior of the shell by a small spring a0, which tends to move each of the arms 4E3 inward. The hooks or projections A15 in each shell are arranged in different planes, that representing the key of the highest value occupying the lowest plane, while that representing the key of the lowest value occupies the highest plane, those representing the keys of the intermediate values being arranged equidistant between the two extremes. \Vorking behind all of the shells 10 is a concentrically-swinging bar 4C7, carried on arms L8, mounted on the shaft 3i). The bar 47 extends entirely across the machine and in its movements concentrically to the shells etl) clears the projections or hooks 15 when the latter occupy their normal positions. The bar 47 is actuated by the till-cover or other manuallyoperated device to make a complete up-anddown movement corresponding with each sale. One of the arms &8 at each side may therefore be connected by links $5) with an arm 50, carried by slides 12. In order to effect movement of one or more of the arms 1?) by the depression of the proper keys, .1. interpose between the keys and said arms a,plurality of tilting levers 51, having curved-n1)ward ends normally out of engagement with the arms L?) and seated on a flat stationary bar 52, said tilting levers being connected to the key levers and being maintained by springs 53, normally seated on the bar By depressing any one of the keys the correspomling tilting lever 51 will be moved downward on the bar 52 and its upper end will be moved inward into engagement with the corresponding arm a3 to project the corresponding hook or projection outwardly. The depressed position of the .key and tilting lever is shown in dotted lines in Fig. 3. Movement of the shell 10 corresponding to the units-bank is communicated directly to the units-disk of a suitable register, that of the tens-bank to its disk, and of the hundreds-bank to the hundreds-disk. This may be done by mounting a gear-wheel 5a on the shaft 39 adjacent to the units-disk, a corresponding gear-wheel being also loosely mounted on said shaft adjacent thereto for connection with the tensbank of keys. One of the arms a1 is prolonged at 56 and carries a pawl 57 for operating the gear-wheel 54:, while one of the arms of the tens-bank is prolonged at and carries a pawl 59 for rotating the gear-wheel These pawls are actuated by light springs to, carried on the arms 56 and 58. The shell 10 for the hundreds bank of keys operates through a suitable pawl a gear-wheel (31, which meshes with a gear (52 on counter-shaft 63. The gears 54: and mesh with and drive smaller gears 64: and (55, respectively, preferably of half the number of teeth as the driving-gears, and the counter-shaft (53 also carries a gear (56 with 'n'e'ferably the same number of teeth as the gears 6st and 65.

These gears 64, 65, and 66 operate the totalregister. This comprises a suitable frame 67, carrying a shaft 68 therein directly above the counter-shaft 63, to which the gear 66 is keyed and on which the gears 64 and 65 are loosely mounted. On the shaft 68 are loosely mounted disks 69, 70, 71, 72, 73, and 74, representing units, tens, hundreds, thousands, tens of thousands, and hundreds of thousands. Manifestly the number of these disks is immaterial. Each disk carries on its periphery the representations of the nine digits and the cipher arranged in sequence. Each of said disks is provided with a web and an annular flange 76, so that they are essentially hollow. Mounted upon the shaft 68 within each of the disks is a small collar 77, secured to said shaft by a key 78. Each of said collars carries a spring-pawl 79, adapted to engage with a tooth or projection 80, formed on the inner side of the annular flange 76 of each disk. The shaft 68 may be rotated by a milled wheel 81, whereupon the collar 7 7 will be turned to engage the pawls 79 with the teeth 80 for simultaneously moving all of the disks around to zero. The shaft 68 is normally held against rotation in any suitable wayas, for instance, by means of arms 82, mounted on pivots and connected together bya rod 83, said arms engaging notches 84 84, Fig. 7, in two disks 85, keyed to the shaft. The arms 82 are normally depressed by means of springs 86. The units, tens, and hundreds disks 69, 70, and 71 are each provided with a ratchet-wheel 87 and a gear-wheel 88. The gear-wheels 88 of these disks are engaged with and driven by the gear-wheels 64, 65, and 66. The disks 72, 73, and 74 are provided with ratchet-wheels 89, 90, and 91, respectively, but are not provided with gear wheels. Backward movement of all the disks is prevented by means of spring-pressed pawls 92 engaging the ratchet wheels 87,89, 90,and 91, respectively. In order to carry from units to tens, from tens to hun- (l reds, from hundreds to thousands, and so on,

I employ carrying-pawls 93 (shown more particularly in Fig. 3) in line with the ratchets 87 of the units, tens, and hundreds disks. The said carrying-pawls are normally elevated from engagement with the ratchet-wheels by pins 94, carried on small slides 95, working in guideways in the frame of the register. These slides are moved downward when released by springs 96. They are held in a normal elevated position by a catch 97, carried on a horizontally-moving rod 98, moved normally outward by a spring 99. (See Fig. 3.) Each of the gear-wheels 64, 65, and 66 is provided near its periphery with two pins 100, arranged in the path of movement of one of the rods 98, so that when either of said gearwheels has moved its corresponding disk to a position to show the figure 0 one of said pins will have engaged the rod 98 of the wheel of the disk of the next higher .denomination to l release the same and allow the spring 96'to move the slide downward. This allows the carryingpawl 93 to engage with the ratchet 87 of the desired disk. If now the pawl is actuated to the proper extent, the disk of the next higher denomination will be advanced one step. To effect this end, 1 connect each of the carrying-pawls with a swinging arm 101, carried on a shaft 102 and each having a rearwardly-extending cam-surface 103. Mounted beneath and behind the shaft 102 is a rotating shaft 104, carrying cam-fingers 105, which successively engage the cams 103. The shaft 104 in making a complete rotation will cause the cam-fingers 105 to successively engage cams 103, and the three carrying-pawls will hence be successively moved. Mounted behind the shaft 104 is a shaft 106', carrying a ratchet-wheel 107, havingfour teeth 108. The shaft 106 has keyed to it a gear-wheel 109, meshing with a pinion 110, keyed to the shaft 104 and of one-fourth the size thereof. An arm 111 is mounted on the shaft 106 and moves radially thereon, said arm carrying a pawl 112, adapted to engage with one of the teeth 108. Return movement of the ratchet-wheel 107 is prevented by means of a pawl 113. The arm 111 is moved at each sale by means of the pitman 114, connected at its upper end and attached at its lower end to the tablet-elevating bar 14. In order that return movement of the carrying-pawl by the effect of a spring 115 may elevate its particular slide 95, I provide each of said carrying-pawls with a linger 116, which engages beneath the pin 94. It will be observed upon reference to Fig. 3 that when the carrying-pawl has been tripped to fall to the position shown in dotted lines it will in being moved forward by the engagement of one of the cam-fingers 105 have its rear end elevated .by the swinging of the arm 101 on the support 102, and as the finger 116 engages beneath the stud 94 the slide 95 will be elevated and locked in its elevated position by the catch 97.

When it is desired to reset the register to zero, the carryingpawls are prevented from dropping into engagement with the ratchetwheels 87 and are held elevated in inoperative position by their respective slides 95. To efwith an angular arm 117, having a hook 118 at its upper end. The aforesaid rod 83 passes under all of the hook-arms 118, so that when it is elevated it will engage said hook-arms feet this result, each of theslidesis provided the transfer-pawls will all remain in their normal positions.

In carrying from the hundreds to the succeeding disks ofhigher;denomination I provide the carrying-pawl for said hundred s-d isk particularly in Fig. 5, and the ratchet-wheels 89 and 90 are provided each with a very deep notch 122, in which either of the lingers 119 or 120 may engage, as is common. In normal operation the linger 119 will engage only with the ratchet-wheel 89, the lingers 120 and 121 being elevated above the ratchet-wheels 90 and 91, respectively." \Vhen. however, the linger 119 engages with the deep tooth 122 of the ratchet-wheel 89, it will allow the linger 120 to engage with the teeth of the ratchetwheel 90; but the linger 121 will still be elevated above the ratchet-wheel 91. If, however, the deep teeth 122 of both of the ratchetwhecls 89 and 90 are in line with the lingers 119 and 120, the said lin ers will drop s'ullieiently low to allow the linger 121 to engage the teeth of the ratchet-wheel 91. In this way in the manner to be explained I provide for a very simple carrying between the disks of the higher denominations.

The operation of my improved device will be as follows: Normally the till-cover will be in an elevated position to protect the till and be lockedas, for instance, by the engagement between the lockinglip 29 and the toothed plate 30. The tablet-rods will be in their depressed positions and the keys elevated with the lugs 33 beneath the lockingplates 3&. The several semicylindrieal shells M) will be in their lowermost positions with all of the hooks or projections 45 in their innermost positions in contact with the peripheries of said shells. The several disks of the totalizing-register indicate ZOI'O. The carrying-pawls 93 and lingers 119, 120, and 121 are also elevated. Upon depressing one of the keys 25 the lug 33 thereof will elevate the particular locking-plate 8 1 for the bank in which the key is located, which locking-plate will drop down behind said lug to lock the key in its depressed position. The curved linger or arm 32 of the key moves the trip 19 ot' the proper tablet-rod into the path of movement of the tablet-elevating bar let and holds said trip in that position. The depression of the key also operates the proper tilting lever 51, which engages with one of the arms or levers 43 to project the hook 45 into the path of movement of the swinging bar 4:7. The depression of the key also depresses the rod 2 1 to retract the tablet-locking bar 20 and to release any tablet or tablets which may be elevated to indicate a previous sale. The movement of the bar 2 1 also disengages the lip 29 from the locking-plate 30 curved arm-32 oi the depressed key.

to release the till-cover. The till-cover is now opened, or any other manually-operated movement takes place and elevates the levers 9 at the sides of the machine to raise the slides 12, carrying the tablet-elevating bar 14.. This tablet-ole 'ating bar will in its upward movement engage beneath the trip 19, which has been operated, and by reason of the hooked end of said trip the latter will be prevented "from returning to its normal position when it is moved from out of engagement with the \Vhen the tablet-rodhas been elevated almost to its full extent, the cam-arms 38 on um tabletclevating bar will engage the cams 37 to elevate all 01 the locking-plates 3e, and any key or keys which may have been depressed and locked will be released. This movement allows the bar 24 to be elevated. placing the lip 29 in position to again lock the till-cover when it is returned to its normal position and also returning the tablet-locking bar 20 into position to engage beneath the lug 21 on the tablet-rod which is being elevated, whereby ythe tablet-rod will be locked in its elevated position and will indicate the amount of the sale. The elevation of the slides 12, through the links 4.9, will swing the bar 17 radially on the shaft 39, and said bar will ei'igage beneath the hook or projection 15 which may have been operated. This engagement causes the shell 10, representing the particular bank in which the operated key is located, to be moved radially, and although the arm 41:1 will be thus moved out of engagement with the tilting lever 51 the said arm 4C1 will be prevented from returning to its normal position by reason of the engagement between said hook and the bar 4.7. The return of the operated key, which takes place near the end of the movement of the till-cover, returns the tilting lever 51 to its normal position. Although the movement of the bar 17 is constant, the movement of the shells M) is variable and depends upon the location of the hook or projection 4E5 which maybe actuated. hen the key of the highest denomination is depressed, the bar 17 will engage with the hook or projection representing that key immediately after the said bar starts to move, so that the shell 40 will be moved almost to the full extent of the movement of said bar, in the present instance to an extent equal to nine of the teeth of the gear-wheel 54:, 55, or 61. If, however, the key representing the lowest value is depressed in either bank, the bar at? does not engage with the hook or projection representing that key until the said bar has almost completed its movement, so that the shell 40 which is operated will be moved to an extent equal to only one of the teeth of any of said gears. Assuming that a sale of nine cents has been made, the key designated 9 in the unitsbank will be depressed, and upon the opening of the till-cover the bar 17 will engage with the particular hook or projection 45 immediately after the said bar commences to move, so that the shell of the units-bank will be moved to an extent to rotate the gear-wheel 54 nine teeth. This movement will be communicated, through the gear 64, to the gear 88 of the disk 69, and said disk will hence be moved from the Zero position to disclose the figure 9, indicating the amount of the sale. If the next sale is five cents, the proper key of theunits bank will be depressed and the shell 40 of that bank will be moved to an extent to rotate the gear 54 five teeth. This movement will rotate the gear 88 of the disk- 69 to a corre sponding extent and the number 4 will be disclosed on said disk. During this movement, however, one of the pins 100 on the gear 64 will have engaged and tripped the rod 98 of the carrying pawl for the tens-disk, allowing the slide 95 to be depressed and allowing the carrying-pawl 93 for the tens-disk to engage with the ratchet 87 of said disk. Upon the return of the till-cover to its normal position it will be locked by the engagement of the locking-lip 29 with the plate 30. This movement lowers the slides 12'from engagement with the trip 19 of the operated tablet-bar; but the said tablet-bar will be kept in its elevated position by the tabletlocking bar 20. The downward movement of the tablet-elevating bar 14, through the link 8 and pawl 112, causes the ratchet-wheel 107 to move one-fourth of a rotation, rotat ing the pinion 110 a complete turn and causing all of the cam-fingers 105 to engage with the cams 103 of the three swinging arms 101 to actuate all of the carrying-pawls. Only one of said carrying-pawls, however, has been depressed, and. that is the pawl for the tensdisk. This movement will therefore advance the tens-disk one step, so as to disclose the figure 1,the tens and'units disks therefore indicating 14, the sum of the two sales.

The movement of the carrying-pawl 93 for the tens-disk, through the swinging arm '101, therefore elevates the rear end of said carrying-pawl, and the finger 116 engaging beneath the pin 94 will elevate the slide 95 until it is locked by the catch 97. In carrying from tens to hundreds the same operation takes place, except that the carrying-pawl for the hundreds-disk is released to engage with the ratchet-wheel thereof by means of one of the pins engaging the bar 98 for said hundreds-disk. It will therefore be seen that upon each downward movement ofthe tillcover the pawl 112 is moved up toengage one of the teeth 108 of the ratchet-wheel 107 and that upon each closing movement of the tillcover said pawl rotates the ratchet-wheel107 one-fourth of a rotation to effect a complete turn of the pinion 110, and to thereby cause all of the cam-fingers to actuate all of the carrying pawls. Said carrying-pawls are, however, rendered active for the purthe immediate lower denomination.

pose of carrying upon a disk of higher denomination only when they are allowed to come into engagement with the ratchet-w heel of said disk by mechanism actuated by or through the instrumentality of the disk of In carrying from the hundreds to the thousands and succeeding disks the carrying-pawl having the three'fingers 119, 120, and 121 comes into play. In carrying from the hundreds-disk to the thousands-disk the said pawl will be released and the finger 119 will engage with one of the shallow teeth of the ratchet-wheel 89. to advance the disk 72 one step. When, how- .ever, the disk 72 indicates 9, the finger 119 will drop into the deep tooth 122 on the ratchet-wheel 89 and allow the linger 120 to engage one of the shallow teeth of the ratchetwheel 90, so that upon the movement of the carrying-pawl the fingers 119 and 120 will simultaneously advance both of the disks 72 and 73 one step. When, however, both of the disks 72 and 73 represent 9 or 99 in the total, the fingers 119 and 120 will both drop into the deep teeth 122 of both of the ratchet-wheels 89 and 90, allowing the finger .121 to engage one of the teeth of the ratchetwheel 91, so that upon the operative movement of the carrying-pawl all of the fingers will advance the disks 72, 73, and 74 one step.

When it is desired to reset the totalizing-register, this is done by rotating the milled wheel 81 in the direction in which the said disksrotate. This rotates the shaft 68 until all of the pawls 79 come into engagement with the teeth 80 of the several disks, and the said disks will then be moved simultaneously, all indicating the same figure, until they all designate zero. When a sale requiring the depres sion of a key in each of several banks is madeas, for instance, one dollar and ninety-five centsthe operations described are simply repeated in the aggregate. In this instance the pressed, actuating the projection or hook 45 occupying the highest plane on the shell 40: of that bank, said key being locked, as explained, and operating the trip of the proper tablet-rod. The key marked 9 of the tensbank is depressed, actuating the hook or projection occupying the lowest plane in the shell 40 of that bank, said key being also locked and operating the trip of the proper tabletrod. The key marked 5 of the units-bank is also depressed and locked, operating the trip of its proper tablet-rod and also moving outward the hook or projection 45 occupying the intermediate plane of the shell of the units-bank. The movement of any one of these keys will obviously release the till-cover.' When the till-cover is moved downward to disclose the till, the tablet-bar 14 will be elevated to disclose all of the tablets the tripsof which have been actuated, and said tablets'will indicate the amount ofxthe sale.v Theupward key marked 1 of the dollar-bank is demovement of the slides 12 will swing the bar 4L7 concentrically to the three shells 4:0. Said bar will lirst engage the hook or projection of the tens-bank, and the shell 4:0 of that bank will be moved to an extent to rotate the gear 55 nine teeth, thereby l'noving the gear 88 of the disk '70 the same number of teeth, and assuming all the disks to be normally at zero the said tens-disk will first show the figure 9. The movement of the bar 47 will next engage thehook or projection a5 of the unitsbank, and the shell 40 of that bank will be moved to an extent to rotate the gear 5 L live teeth. This movement will rotate the gear 88 of the disk 69 five teeth, and the said disk will disclose the figure 5. \Vhen the bar a7 has almost completed its movement, it will engage the hook or projection 45 of the dollarbank, and the shell 40 of that bank will be moved to an extent to rotate the gear 61 one tooth, which movement, communicated through the gear 62, counter-shaft 63, and gear 66, will move the gear 88 of the disk 71 one tooth, and the latter disk will disclose the ligure l, the three disks therefore indicating 195. the amount of the sale. In none of these movements will the carrying-pawls be actuated, although upon the return movement of the till-cover the pawl 112 will rotate the ratchet-wheel 107 one-fourth of a rotation, giving a complete turn to the pinion 110 and causing all of the cam-fingers 105 to move all the carrying-pawls, which being out of engagement with the ratchet-wheels of the tens, hundreds, and thousands disks do no affect any movement of the latter.
